To all 'whom t may concer/n.'

Be it known that I, CLARENCE C. C. Ille- Gnns, a citizen of the United States, residing at Hooper, in the county of Dodge and State of Nebraska, have invented certain new and useful Improvements in Torches, of which the following` isl a specification.

This invention relates to torches for removing paint or for use in brazing or soldering and for other purposes where a high heat is necessary. The invention seeks to provide a device which may be produced and operated at a low cost and which will not be apt to get out of order but may be easily repaired, should repairs be necessary. The invention also seeks to provide a `device which, while simple in the construction and arrangement of its parts, will be efficient in use and economical in the consumption of fuel.

The invention is illustrated inthe accompanying drawings, in which- Figure 1 is a sectional elevation rof a torch embodying my improvements;

Fig. 2 is a plan view of the same;

Fig. 3 is an enlarged detail section of the regulating valve.

In carrying out my invention, I employ a tank 1 which is provided in its top with a central internally threaded opening 2 but is otherwise imperforate. I also employ a T-coupling 3, the shorter branch 4 of which is externally threaded to engage in the internally threaded opening 2 in the tank and is provided with an annular stop shoulderV 5 so that, while the elbow may be engaged in the opening 2 firmly, it will be prevented from being turned sofar as to strip the threads. The said stop shoulder by contaeting with the top of the tank or the boss thereon surrounding the opening 2 prevents the tube 6, depending from the branch 4, being driven against the bottom of the tank and thereby damaging it. This tube 6, as clearly shown in Fig. 1, is of small bore and it may be formed integral with the elbow 3 or connected therewith by screw threads, as will be readily understood. To one end of the coupling 3, I connect a handbperated pump 7, by the manipulation of` which air may be forced into the tank through the tube 6 so as to rise through the body of fuel and accumulate at the top of the tank to eX- ert pressure upon the fuel. To the opposite end of the coupling 3, I secure an elbow 8 in which is swiveled .one end of the delivery tube 9, the said end being disposed at an angle to the main length of the tube, as clearly shown in Fig. 2. This tube 9 is also constructed to form or has coupled thereto a valve casing 10 in which is mount ed a needle valve 11 adapted to close a port 12in a( partition 13 within the casing, thereby cutting off the flow of fuel from the tank through the tube. In the operative position ofthe torch illustra-ted in the drawings, the tube 9 enters the valve casing 10 the side thereof and from the bottom of the valve casing depends one branch 14 of a Ui-shaped burner tube 15. The end of the said burner tube, more remote from the valve casing, has coupled thereto a coil 16 constituting the burner, said coil having its terminals brought together and coupled to the tube 15 by a collar or nut 17, as will be readily understood. In the inner circumferential wall of the coil is a jet opening 18 through which the vaporized fuel or c0m bustible may escape.

The use` of the device will, it is thought, be readily understood. The coupling 3 is removed from the opening 2 and the fuel, such as gasoline or other hydrocarbon, is poured through the opening 2 to fill, the tank. The feeding tube 6 is then inserted through the opening 2 and the coupling 3 turned home, thereby causing the tube 6 to pass downwardly through the fuel in the tank and come to rest with its terminal disposed adjacent the bottom of the tank. The pump Z7` is then manipulated to force air into the tank to the desired pressure, whereupon the device will be ready for use. llVlien the use of the device is desired, the needle valve 11 is withdrawn from its seat so as to permit the fuel to pass from the tank under the action of the` air trapped in the tank and-fill the U-shaped burner tubel 15. Any convenient small liame may be held to the burner` coil 16, it being understood that the needle valve is closed after the burner tube. is filled, until the fuel which .begins to issue through the jet 18 starts to burn. `The valve 11 may then be opened so as to permit the fuel to flow' to and through the burner tube inthe desired volume and, as it issues through the rjet 18, it will be at once ignited and will burn with an intense flame. This flame will play upon the coil 16 so as to heat the same and cause the fuel therein to be vaporized and will also be spread by the coil so that a surface of appreciable area may be subjected tothe action of the flame.

It will be readily noted that the fuel passes from the tank through the same element that admits the inflowing air to the tank and that the inflowing air is delivered at the bottom of the tank. As a result of this arrangement, the air flowing to the top of the tank will aerate the fuel and, when the needle valve is open, the expansion of the air will cause partly miXed air and fuel to flow upwardly through the tube 6 into the coupling 3 and thence past the needle valve to the burner tube and burner coil. The tortuous path over which the escaping air and fuel is thus caused to travel will effect a thorough mixing of the same so that when subjected to the heat playing upon the burner coil, the fuel will be very completely and effectually vaporized and will burn steadily and economically at the issuing jet. It will also be readily noted that my device is exceedingly simple in the construction and arrangement of its parts and may be produced at a very low cost. All the working parts are carried by the T-coupling 8 so that they may be removed from the tank or fitted in working position thereon by merely rot-ating the said coupling so as to effect engagement of its threads with the threads in the opening 2 of the tank. The barrel or cylinder of the pump 7 may be utilized as a handle for the device and when the device is in use the burner tube l5 will rest against the side of the tank so as to be supported inoperative position, as shown in Fig. l. In this position of the burner tube, it will be noted that the burner coil forming the terminal of the tube is disposed in such a position that the flame therefrom may be easily directed against the work, and the inner shorter arm of the burner tube rests against the side of the tank so that the tube will be supported in the working position in such a manner that it cannot be'readily put out of place by a chance blow and without subjecting the swiveled joint to excessive strain, the weightof the burner being partially sustained by the tank. When the device is not in use, the swiveled joint between the tube 9 and the branch 8 permits the burner to be swung over the tank and assume a position above the same so that it will be out of the way. When the burner tube is swung into inoperative position above the tank, the outer arm of the U-shaped portion of the tube will bear against the side of the tank da metrically opposite the point at which the burner was supported when operating, so that the upper corner of the tank will be between the branches of the U-shaped pipe.

lThe burnertube may be thus brought close to the tank and disposed within the area defined between the elbow 8 and the outer end of the pump so that it will be out of the way when the torch is to be put aside. This movement of the burner tube and the attached parts will also permit the fuel which may have been trapped in said tube to be drained back into the tank and after it has been so drained back into the tank the closing of the needle valvell will prevent escape of the volatile fuel so that loss of fuel will be prevented. rlhe air pump 7 is, of course, manipulated from time to time to re-establish the pressure in the tank after the same may have been diminished through withdrawal of fuel.

Having thus described the invention, what is claimed as new is:

l. A torch comprising a tank having a single opening through its top and being' otherwise imperforate, a T-coupling having` its lateral branch fitted in the opening in the top of the tank, a pump carried by one endof said coupling and disposed radially over the top of the tank, and a burner carried by the opposite end of said coupling, the pump and the burner being in communication with the coupling and through the coupling with the tank.

2. In a torch, the combination of a tank, a T-coupling fitted to the top of the tank, a burner tube having a swiveled connection with one end of said coupling, and a pump connected with and carried by the opposite end of the coupling.

3. A torch comprising a tank, a coupling detachably fitted to the tank, an air pump disposed above the tank and carried by one side of said coupling, a burner tube having a swiveled connection with the opposite side of said coupling, a valve in said burner tube to regulate the flow through the same, and a burner coil forming the outer terminal of said tube.

4. A torch comprising a tank, a coupling detachably fitted to` the top of the tank, a burner tube having a member swiveled to one side of said coupling, a valve mounted in said member, the burner tube having a U-shaped portion normally depending from said valve, a burner coil forming the outer terminal of said U-shaped portion, and an air pump disposed above the tank and carried by said coupling at that side of the same opposite the burner tube.

In testimon whereof I affix my signature.
